and access times of a file to the value specified by the times argument
under the following constraints,
- The times argument is not null,
- The user ID of the process is not "root".
- The file is owned by the user ID of the process.

and access times of a file to the current time, under the following
constraints,
- The times argument is null.
- The user ID of the process is not "root".
- The file is not owned by the user ID of the process.
- The user ID of the process does not have write access to the
file.
2. Verify that the system call utime() fails to set the modification
and access times of a file if the specified file doesn't exist.
vfork01
Fork a process using vfork() and verify that, the attribute values like
euid, ruid, suid, egid, rgid, sgid, umask, inode and device number of
root and current working directories are same as that of the parent
process.
vfork02
Fork a process using vfork() and verify that, the pending signals in
the parent are not pending in the child process.
vhangup01
Check the return value, and errno of vhangup(2)
when a non-root user calls vhangup().
vhangup02
To test the basic functionality of vhangup(2)
wait02
Basic test for wait(2) system call.
wait401
wait401 - check that a call to wait4() correctly waits for a child
process to exit
wait402
wait402 - check for ECHILD errno when using an illegal pid value
waitpid01
Check that when a child kills itself by generating an alarm
exception, the waiting parent is correctly notified.
waitpid02
Check that when a child kills itself by generating an integer zero
divide exception, the waiting parent is correctly notified.
waitpid03
Check that parent waits unitl specific child has returned.
waitpid04
test to check the error conditions in waitpid sys call
waitpid05
Check that when a child kills itself with a kill statement after
determining its process id by using getpid, the parent receives a
correct report of the cause of its death. This also indirectly
checks that getpid returns the correct process id.
waitpid06
Tests to see if pid's returned from fork and waitpid are same.
waitpid07
Tests to see if pid's returned from fork and waitpid are same.
waitpid08
Tests to see if pid's returned from fork and waitpid are same
waitpid09
Check ability of parent to wait until child returns, and that the
child's process id is returned through the waitpid. Check that
waitpid returns immediately if no child is present.
waitpid10
Tests to see if pid's returned from fork and waitpid are same
waitpid11
Tests to see if pid's returned from fork and waitpid are same
waitpid12
Tests to see if pid's returned from fork and waitpid are same
waitpid13
Tests to see if pid's returned from fork and waitpid are same
write01
Basic test for write(2) system call.
write02
Basic functionality test: does the return from write match the count
of the number of bytes written.
write03
Testcase to check that write(2) doesn't corrupt a file when it fails
write04
Testcase to check that write() sets errno to EAGAIN
write05
Check the return value, and errnos of write(2)
- when the file descriptor is invalid - EBADF
- when the buf parameter is invalid - EFAULT
- on an attempt to write to a pipe that is not open for reading - EPIPE
writev01
Testcase to check the basic functionality of writev(2) system call.
writev02
In these testcases, writev() is called with partially valid data
to be written in a sparse file.
writev03
The testcases are written calling writev() with partially valid data
to overwrite the contents, to write in the beginning and to write in
the end of the file.
writev04
The testcases are written calling writev() with partially valid data
to overwrite the contents, to write in the beginning and to write in
the end of the file. This is same as writev03, but the length of
buffer used here is 8192 bytes.
writev05
These testcases are written to test writev() on sparse files. This
is same as writev02. But the initial write() with valid data is
done at the beginning of the file.
